TLC's Half-Ton Killer tells shocking tale of 1,100lb woman who confessed to killing her nephew - until her weight proved testimony was a LIE

A new documentary is set to reveal the astonishing true life story of a woman who testified falsely to murder but was found innocent on the grounds that her burgeoning obesity could never have allowed her to commit the crime.TLC's Half-Ton Killer? tells of how, in March 2008, Texan Mayra Rosales, 31, told police officers that she had killed her two-year-old nephew, Eliseo Jr, by accidentally rolling on top of him while babysitting. Such was her 1,100lb frame, Mayra imagined her story to be believable, but after doctors revealed that the boy could only have died from a blow to the head, the reality that she was so big she couldn't move her arm, became her attorney's main argument for her defence.

I should be punished, I did wrong,' Mayra sobbed at the time as law enforcement officials took her tears to be those of guilt and a media storm was ignited.'Why isn't this woman in jail?' Demanded Nancy Grace at the time.

'Could they even give her enough poison to execute her,' asked another pundit.But there was more to the story than met the eye, her attorney Sergio Valdez realised, after doctors announced the cause of Eliseo's death.

You see all that fat to the rear? If she was to get touched there, would she feel it as strongly? Or feel it at all? On those parts of her, is her sense of touch more minimal due to the pathways it would need to get to her brain? A much longer pathway, I presume.

You don't often see a woman who could double as a bedspread.... On the plus side, she could be the difference between life and death in a survival situation. That leg fat could serve as a nice warm cocoon.
